Usage
Information
Route prefixes stored in the L3 host table are managed using ECMP next-hop forwarding.
A warning message is displayed after you enter the command stating that this setting takes effect for
existing routes only when IPv4 route prefixes are cleared from the LPM routing table (RTM). To enable
storage of IPv4 route prefixes in the LPM table, disable this setting by entering the no ipv4 unicast-
host-route command.
Example
Dell(conf)#ipv4 unicast-host-route
Warning: Command will take effect for existing routes only when IPv4
route prefixes are cleared from RTM
Dell(conf)#no ipv4 unicast-host-route
load-balance
By default, the system uses an IP 4-tuple (IP SA, IP DA, Source Port, and Destination Port) to distribute IP traffic over members
of a Port Channel as well as equal-cost paths. To designate another method to balance traffic over Port Channel members, use
the load-balance command.
C9000 Series
Syntax
load-balance {ip-selection [dest-ip | source-ip]} | {mac [dest-mac |
source-dest-mac | source-mac]} | {tcp-udp | ingress-port [enable]}
